I'd found it by looking at various reviews of "best OpenWrt = router for 2021". I just updated my Zyxel firmware from v18 to v20 = firmware. I get about 280 Mbps from Xfinity. I turned on cake and it = dropped by 50%! So I think the old router's CPU isn't up to it. I'll be = swapping in the TP-Link soon so I can turn on cake without the big = performance hit. Getting low latency traffic shaping to work in a robust and = reliable way above say ~100Mbps is still a challenge even for relatively = recent router SoCs. Modern multicore SoCs upped the ante in the = things-to-look-out for area by adding CPU power-saving (especially = frequency scaling) and load distribution over CPUs to the mix... Now = even something like a raspberry pi 4B with an additional well-selected = USB3 gigabit ethernet dongle (costing less than 100 EUR all in all) will = allow cake up to 1/1 Gbps but still requires careful configuration to do = so. No idea whether an archer 20 will do (not even sure what model that = is, here in Germany I see either an C20 or an AX20 but no plain = unadorned 20). If you should try OpenWrt on that thing, the OpenWrt = forum is a good place to ask for configuration advice for specific = models (will obviously not help if you stick to the manufacturer's = firmware).
